The SP ATC (Advanced
Tactical Compensator) was engineered using CFD analysis software to
design the best compensator available. SP’s unique side port design
minimizes recoil as well as muzzle rise. Instead of allowing the first
port to do the majority of the work our proprietary front facing ports
spread out the load minimizing felt recoil and reducing muzzle flash.
Instead of using a crush washer, included is a knurled jam nut to make
installation and removal for cleaning a breeze. No special gunsmithing
is required. The SP ATC is available in either 1/2-28 threads
for.223/5.56 or 5/8-24 for up to 30 cal. The ATC-AR brake is designed to
be used on barrels with muzzles no larger than .750 (most common gas
block size).
